prophylactic anticoagulation


Also found in: Dictionary, Thesaurus.

prophylactic anticoagulation

The administration of anticoagulant drugs to patients who have a high risk for venous thromboembolism, e.g., patients admitted to medical wards of hospitals or undergoing certain forms of surgery, esp. on the hips or knees.

CAUTION!

The practice reduces the likelihood of the formation of blood clots but increases the risk of bleeding.

Specifically, to our knowledge, our study is the first to show that patients receiving current treatment for cancer are at increased risk for PICC-associated DVT and that this risk is not reduced by the use of commonly used prophylactic anticoagulation.
Although several studies in patients with malignancy and nonperipherally inserted central venous catheters suggest that prophylactic anticoagulation with low-dose warfarin may reduce the incidence of DVT, (14,15) a more recent prospective trial of low-dose (1 mg) unmonitored warfarin therapy performed by Heaton and colleagues showed no reduction in the risk of thrombosis in cancer patients with central venous catheters.
The lack of benefit of one prophylactic anticoagulation regimen (1 mg a day of unmonitored warfarin) in this patient cohort may be related to the nature of the peripheral catheter.
Our investigation suggests that one commonly used prophylactic anticoagulation regimen in these higher risk patients may not be effective.
Although pre-operative initiation of prophylactic anticoagulation is desirable, there are data indicating that starting prophylaxis postoperatively is adequate.
Sub-group analysis showed prophylactic anticoagulation may decrease the RR of VTE with induction thalidomide.
